I've enjoyed the book very much. It's highly entertaining and a quick read. I'd agree with Marc's comments. Some of his formula, while intriguing, will likely not be of much help to many. However, it has served as a seriously needed kick in the butt for me with regards to becoming much more scrupulous about what I allow into my life and onto my radar. One thing about GTD is I have becoming very good at managing 100's of projects, but I'm not so great at determining whether I should be managing all of them in the first place.Also, it has(at least in the short term) left me determined to stop allowing myself to be seduced by the siren song of yet another gadget/software/doodad to help me better manage those 100's of projects.
In the last two weeks I have sliced about 1/4 of my projects off my lists and either just let them go (through renegotiation with myself of others), delegated them, or parked them on my someday list.
And I've made some real progress in terms of the amount of time I spend reading RSS feeds and trolling forum and web sites. (This is my first time here in a week-a new record)
Anywho, a good investment in my books
